Anti-jamming device in the field of motor vehicles

Abstract

The invention relates to an anti-jamming device in the field of motor vehicles, which is used for preventing an object from getting caught. Said anti-jamming device comprises an actuating means (1) which can be coupled to a body part (3) of a vehicle and can be moved relative to said body part (3) by resting the same against the object, and an apparatus for detecting a relative movement between the actuating means (1) and the body part (3).

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a 35 U.S.C. §371 National Stage entry of PCT / DE2006 / 001427, filed Aug. 14, 2006, which claims priority from German Patent Application No. DE 10 2005 038 617.2, filed Aug. 16, 2005, the contents of which are herein incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to an anti-trap device in the field of motor vehicles for preventing trapping of an object.[0004]2. Description of Related Art[0005]Although applicable to any desired movable components, the present invention and the problem on which it is based are explained in more detail on the basis of a body part in the field of motor vehicles, and in particular with regard to a rear flap of a vehicle.SUMMARY OF THE INVENTION[0006]In order to improve the operating comfort of motor vehicles and in particular of passenger vehicles, an increasingly large number of manually-driven components have in past ye...

Benefits of technology

[0023]In each case one leader strip is for example pivotably attached by means of in each case one associated fastening strip or directly in the region of the longitudinal side of a rear flap of a vehicle. In this way, a risk of injury on account of, for example, a trapped body part is reduced at both longitudinal sides of a rear flap during a closing movement of the latter.

[0024]According to a further preferred exemplary embodiment, the detection device is embodied as an electric mechanical or electromechanical inductive switch or the like, for example as a microswitch or proximity switch, which can be attached to the body part, to the actuating means and / or to the fastening strip. The detection device can for example be embodied as a switch of which the guide means, advantageously a steel guide bolt, forms a constituent part, for example the mating contact face of a microswitch or a constituent part of a Hall sensor. In this way, a relative movement between the actuating means and the fastening strip or the body part is detected quickly and reliably in a simple and cost-effective manner, so that the drive mechanism for an adjustment of the body part can quickly and reliably be deactivated in order to stop the movement of the body part.

[0025]It is alternatively or additionally possible for the detection device to be embodied as a tactile sensor strip as well which can be attached to the face, which comes into contact with the object, of the actuating means. In this way, the drive mechanism can be deactivated in good time in order to stop the movement of the body part in the event of the clamped object coming into contact with the sensor strip.

[0026]In addition, the detection device can additionally or alternatively also be embodied as a sensor which can be attached to a mating contact section, which is assigned to the body part. It is essential merely that a relative movement between the actuating means and the fastening strip or the body part can be quickly and reliably detected.

[0027]For example, when a relative movement between the actuating means and the body part or the fastening strip is detected, the drive mechanism of the body part can be deactivated in the case of an automatically actuable body part, and a warning signal, for example an audible warning signal, can be generated in the case of a manually actuable body part. The risk of injury is therefore considerably reduced in a simple and cost-effective manner.

[0028]The actuating means and / or the fastening strip are preferably produced from plastic. In this way, the anti-trap device according to the invention can be produced in a simple and cost-effective manner and can be mounted on and retrofitted to a body part using corresponding means.

Problems solved by technology

The additional fastening strip ensures simple retrofitting to for example existing body parts, and therefore complex and expensive retrofitting processes are dispensed with.
